I don’t know why, but the borrow checker doesn’t confuse me that much. Use a reference when you want to see the original memory through a window, move when you want the data for yourself, and never have a window to a place that does not exist.

I think that was the best explanation I've come across so far...you took the time a noobie would need to learn this stuff, and didn't try to "keep under two minutes" destroying the clarity for the sake of speed. Also, you didn't jump immediately to metaphors of "oh, its like if you have a book, and you lend it to someone, but that person can write on the book" and so on...I also find those unnecessary and confusing sometimes

Very nice series As a hobbyist who's dabbled in a bunch of languages because it's fun, i'm now learning me some rust. Certainly doing my share of fighting with the borrow checker but that said, i'm super impressed with the errors and warnings that the compiler spits out. Most helpful messages that i've encountered in any language; have helped me sort out a bunch of things which in other languages i would have had to fire up the google to work out what was going on.

So I recently just made my first foray into Rust by attempting to build a calculator in a Yew app. I am still struggling with the logic itself, but I actually found the battle with the borrow checker to be one of the more refreshing sorts of problems I ran into. It made me think so much harder about where I was declaring my variables and where I was mutating them that it kinda just felt like my brain was steadily increasing in mass and wrinkle count the whole time.

@fennecfox2366 8 ай бұрын

Coming from c++ this is intuitive. Unique pointers and move semantics give this type of behavior as options in modern c++ so having them as the default makes sense. Also having the const as default on refs is another good safety measure. I do think a basic understanding of pointers in c and references and smart pointers in c++ will help people understandownership and the ideas it's built upon.

What I really like about your videos, until now :-), is the speed, you tell things. I'm not native American or English, but most every tutorial I watched for instance on Udemy was so slow. Of cause someone can speedup the video, but sometimes, the speaker speaks faster or changes slides, and that results in confusion. Very, very well done, again until here 🙂as I don't know more of your videos besides the seen ones.

Right around 14:10 was the lightbulb moment for me. And being a long time C and C++ programmer I think I'm finally starting to see why this Rust thing makes sense... What a clever way to make sure that we know who is writing data and who is just reading or calling getters. It makes the C/C++ way of using references, pointers and const seem kind of silly.

You're an amazing teacher thanks man. The way you expained how rust stops two mutable references in the same scope to prevent race conditions. If I am not wrong, this feature isnt there in golang, and this is where rust outshines. This feature will outshine even more, when concurrency comes into play. Explaining why rust promotes safe concurrency. Correct me if I got this right.

Great video. Helped clarify things for me on how this works. Do you guidance on programming styles you recommend when it comes to moving/copying/etc? E.g. when to implement methods as references vs. copies, etc. Side note, the return of the first word function was s.len(), not i. Wouldn't the correct implementation of that return i?

if you cannot remember the ownership rules then here is small trick i thought of which was :- 1) each house has a one owner 2) each house can have only one owner at a time 3) when owner dies the house is broken
